I am sorry, but I put 50/50 fault on you and the Nurse that transferred care to you. The two of you should have thought this out before you loaded the patient. Anytime I did a long distance transport (anything over an hour), I asked these four questions:
1. How have you been managing the patients pain, when was the last dose of meds, do they have enough on board to make the trip (if not, can you please give her another dose, or give me a dose to administer when this wears off).
2. Has this patient had any anxiety issues, sometimes patients who are already anxious get clostrophobic or nervous on long rides (again give them a pill then or one for the road).
3. Has the patient had nausea or vomiting recently, or a history of motion sickness. Patients can get nausous riding backwards for hours.
4. When was the last time the patient went to the bathroom (or when was last time diaper was changed ? (Can we go to the bathroom now, or can you send a couple of diapers with me)
Just because you were ignorant to the fact that you should have asked these questions, does not relieve you of the responsibility of treating your patient. But the good news is that now you have learned from your mistake, and will probably not make it again. This will not be the last time you experience this in EMS, there is no way your employer, your technical school that taught you, or your current training officer can prepare you for everything you will encounter; you have to be able to think on your feet and outside the textbook box.
I am not trying to diss you, if my typed words sound that way, this is just a longwinded way of saying welcome to EMS, own your error, and move on.
